The deferred dividend payments of $3.8 million have been accrued for payment in the future and are being reported for the deferral period as a preferred dividend requirement that is deducted from income for financial statement purposes to arrive at the net income available to common shareholders. Under the terms of the certificate of designations for the Preferred Stock, dividend payments may be deferred but the dividend is cumulative and compounds quarterly while unpaid. In addition, since the Company failed to pay dividends for six quarters, the Treasury had the right to appoint two representatives to the Company’s board of directors.

The Company received no proceeds from the sale and it had no effect on the terms of the outstanding Preferred Stock, including the Company’s obligation to satisfy accrued and unpaid dividends prior to the payment of any dividend or other distribution to holders of junior stock, including the Company’s common stock, and an increase in the dividend rate from 5% to 9%, commencing on February 15, 2014. Further, the sale of the Preferred Stock had no effect on the Company’s capital, financial condition or results of operations. Because of the sale, the Company generally is no longer subject to the various executive compensation and corporate governance requirements to which participants in Treasury’s Capital Purchase Program were subject while Treasury held the Preferred Stock. In addition, the Company has been advised that the current holders of substantially all of the Preferred Stock have entered into agreements with the FRB pursuant to which they have each agreed not to take actions, without the consent of the FRB, which might be construed as exercising or attempting to exercise a controlling influence over the management or policies of the Company or the Bank, including exercise of any right to elect any representatives to the Company’s board of directors. Under the terms of the Company’s and Bank’s Supervisory Agreements with their federal banking regulators as described in Note 13, neither the Company nor the Bank may declare or pay any cash dividends, or purchase or redeem any capital stock, without prior notice to, and consent of, these regulators. Subject to the foregoing, the Preferred Stock may be redeemed in whole or in part, at par plus accrued and unpaid dividends. The Preferred Stock is non-voting (except as described above in respect of the election of up to two directors when preferred stock dividends remain unpaid), other than certain class voting rights. The sale of Preferred Stock did not include the sale of a warrant to purchase 833,333 shares of the Company’s common stock at an exercise price of $4.68, which Treasury continues to hold and may sell in its discretion at any time, subject to applicable securities laws and the Company’s right to repurchase the warrant at fair market value under the terms of the Company’s agreements with Treasury. The warrant may be exercised at any time over its ten-year term and Treasury has agreed not to exercise any voting rights received by acquiring common stock on the exercise of the warrant. The discount on the common stock warrant is being amortized over five years. Both the Preferred Stock and the discount qualify as Tier I capital.
